1. Calculate the speed of both trains. Train A is travelling at 54 km/h, while train B is travelling at 42 km/h.
2. Calculate the time needed for trains A and B to meet. This is equal to (120km / (54+42)) = 1.5 hrs.
3. Calculate the distance Train A has travelled when the trains meet. This is equal to (1.5 * 54) = 81 km.
4. Calculate the distance Train B has travelled when the trains meet. This is equal to (1.5 * 42) = 63 km.
